Dear students, we have to draw the leaf structure of the following, pof3, xco3f2, brcl3, n3 and pf3.
00:09
Starting with pof3, phosphorus is the central atom here and it is having tetrahedral structure and here oxygen.
00:24
Oxygen is having here 6 electrons, fluorine also 6 valence electrons, 7, so 1 is shared with fluorine, sorry, phosphorus.
00:36
So this is the structure and there will be here, this is the coordinate bond, so formal charges will be here minus and this is plus this is p .o.
00:46
F3.
00:47
Now coming to xe o3f2, here jannan three oxen atoms on the equatorial position and one fluorine is here and one fluorine is here.
01:04
More elated negative atom takes the axial positions.
01:09
Now the non -burning electrons are like this.
01:13
Each fluorine is having three pairs of non -burning electrons and each oxen is having two pairs of non -burning electrons and janon is having here extended update.
01:25
Then coming to brcl3, brcl3, bromine is the central atom here and bromine has we know seven electrons in its outermost orbit, 3.
01:39
Three electrons are shared with chlorine and two lone pairs are there.
01:43
So, bromine is having here two pairs.
01:53
This structure is like this.
01:57
So these are chlorine.
02:00
Each chlorine, let us draw like this for chlorine.
02:06
So this is the seven electrons of each chlorine.
02:11
Then this chlorine also having seven electrons, one shared with bromine, and this chlorine is also having 7 electrons shared with bromine.
02:24
In this way, bramine has extended, opted here also, 2 plus 2, 4 and 610, whereas each protein is having 8 electrons in its autonomous orbit.
02:37
Or we can write this as br, cl, cl and cl.
02:48
Now coming to 4th 1, n2, n3, nitrogen, n3...
